IMPROVEMENT IN FLAT-IRON HEATERS.

Specification forming part of Letters Patent N o. 131,202, dated September 10, 1872.

i To all whom it may concern:

Be it known that I, WILLIAM C. WREN, of the city of Brooklyn, State of New York, have invented a new and Improved Furnace for the purpose of Heating Flat-Irons or other uses; and I do hereby declare that the following is a full a-nd exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon making part of this specification.

The nature of my invention relates to using gas or a liquid hydrocarbon in combination with atmospheric air forced into the furnace by artificial means for the purpose of heating the furnace; and it consists in the construction and arrangement of the relative parts hereinafter fully described.

Figure 1 is an eleva-tion. Fig. 2 is a vertical sectional view taken through the center from top to bottom.

The furnace may be made with any number of sides. In the drawing, as shown, I illustrate four.

I construct a furnace, A, with any number of sides, with an opening on each side, shown by the dotted line, Fig. l, over which I place a shield, B, with space of breadth and thickness to receive the body of a iiat-iron, and a slot of sufficient size to allow the handle of the iron to project, so that when the iiat-iron is slid under the shield the face of the iron will be against the side of the furnace, covering the hole spoken of, with the point upward and the heel of the iron will just slip over and rest on the slightly-projecting edge of bottom. E are the legs that rest on the table or bench and hold up the furnace. Gis a firebrick projecting downward from the top of the furnace to within two inches or thereabout of the bottom, and from which the iiame is deected to the chambers B. F is a pipe that comes up through the table, and is screwed into the center of the bottom of the furnace at J, with a blast-pipe, G, of a smaller size arranged inside and extending through or withy the method of operating the same. Having' placed the stove upright over the table, on the legs E, with the pipes F and G in position, as shown, attach the supply-pipe of gas or liquid hydrocarbon (gas made from petroleum is preferable) with the pipe F at H, and a blastpipe with the projecting end of the pipe Gr. The positions of the gas and blast may be reversed, but not with so good a result. Turn on a sufficiency of both gas and air; light it, and the flame will play from the mouth of the pipe against the nre-brick G, and then reverberate downward and outward, through the openings in the body of the furnace, against the face and around the body of the flatirons, and pass off through the slot that takes the handle of the iron, and through the hole K in the top of the shield B.

What I claim as my invention is l. The combination of the fire-brick deiiector G and cap D with a heating-furnace for iiatirons, substantially as described.

2. In combination with the elements of the preceding clause, I claim the arrangement of the blast-pipe Gr, substantially as shown, and for the purpose herein set forth.

WILLIAM O. WREN.
